2G HTS Coils
Industry leaders rely on SuperPower’s second-generation high temperature superconducting (2G HTS) wire to enable significant advances in physics, biology and chemistry research, medical technology and green energy applications.
SuperPower supplies long lengths of high-performance 2G HTS wire to fabricate coils for advanced devices such as HTS magnets, motors, generators, transformers and SMES. 2G HTS wire, as compared with conventional copper, results in more compact coil geometries that allow for greater design flexibility (high field solenoids, race track, etc.) Coils fabricated with SuperPower 2G HTS wire have enormous benefits for research, NMR spectroscopy, high field magnets and energy applications.
SuperPower® 2G HTS Wire delivers performance advantages for your demanding coil applications – enhanced by our expert engineering and design services.
SuperPower® 2G HTS Wire is uniquely suited for coil applications:
• Compact – high engineering current density and half the thickness of most other 1G and 2G conductors
• High-Performance – high strain and strength tolerance compared with most high field LTS, 1G and other 2G wires
• Reliable – superior wire stability and mechanical properties
• Powerful – excellent performance in magnetic fields (high current/energy density)
• Flexible – Suitable for both pancake and layer wound coil types
SuperPower’d expertise, excellence and experience for the advancement of high field magnets:
• 2012 – Brookhaven National Laboratory has advanced superconducting technology to a level that HTS magnets are now being considered seriously in the upgrade of current accelerators, for use in future accelerators and in muon colliders.
• 2012 – a joint research team from the National High Magnetic Field Laboratory, the University of Colorado, and the National Institute of Standards and Technology has successfully demonstrated the world’s first multi-layer electromagnet that was wound from a high-temperature superconducting cable at a field of 20.0 tesla. They also demonstrated a record winding current of 4100 amperes in a single-turn magnet at a background field of 19.81 tesla.
• 2011 – NHMFL successfully tests a superconducting electromagnet to a field of 35.4 Tesla. The new record was achieved with a layer-wound insert magnet constructed with a single piece of SuperPower 2G HTS wire approximately 100 meters in length and nested in a 31 T background magnet.
• 2009 – a coil fabricated and wound by SuperPower and tested at the National High Magnetic Field Laboratory (NHMFL) at Florida State University (FSU), achieved a world record of 27.4 Tesla at 4.2K in a 19.89 Tesla background field
• 2008 – a coil fabricated and tested by NHMFL at 4.2K in a background field of 31 Tesla achieved a world record of 33.8 Tesla at an average winding current density of 459 A/mm2
• 2007 – previous record of 26.8 Tesla in 19 Tesla background was achieved in a coil fabricated by SuperPower
